Experimental implementation of mobile robot taxis with onboard Belousov-Zhabotinsky chemical medium (2004)
Journal Article
Ratcliffe, N., Adamatzky, A., Costello, B. D. L., & Melhuish, C. (2004). Experimental implementation of mobile robot taxis with onboard Belousov-Zhabotinsky chemical medium. Materials Science and Engineering: C, 24(4), 541-548. https://doi.org/10.1016/j.msec.2004.02.002

We discuss the first-ever experimental realization of the onboard excitable chemical controller for stimulus-guided navigation of mobile robots. We demonstrate that the Belousov-Zhabotinsky (BZ) reaction in the form of an onboard thin layer chemical...

Reaction-diffusion navigation robot control: From chemical to VLSI analogic processors (2004)
Journal Article
Rodríguez-Vázquez, A., De Lacy Costello, B., Carmona-Galán, R., Arena, P., Adamatzky, A., Basile, A., …Frasca, M. (2004). Reaction-diffusion navigation robot control: From chemical to VLSI analogic processors. IEEE Transactions on Circuits and Systems I: Regular Papers, 51(5), 926-938. https://doi.org/10.1109/TCSI.2004.827654

We introduce a new methodology and experimental implementations for real-time wave-based robot navigation in a complex, dynamically changing environment. The main idea behind the approach is to consider the robot arena as an excitable medium, in whic...

The formation of voronoi diagrams in chemical and physical systems: Experimental findings and theoretical models (2004)
Journal Article
Purwins, H. G., de Lacy Costello, B., Ratcliffe, N. M., Adamatzky, A., Zanin, A. L., & Liehr, A. W. (2004). The formation of voronoi diagrams in chemical and physical systems: Experimental findings and theoretical models. International Journal of Bifurcation and Chaos, 14(7), 2187-2210. https://doi.org/10.1142/S021812740401059X

The work discusses the formation of Voronoi diagrams in spatially extended nonlinear systems taking experimental and theoretical results into account. Concerning experimental systems a number of chemical systems used previously as prototype chemical...
